1 it may concern:

Be it known that I, THOMAS S. Fametion and then. in another.

My invention is particularly adapted for use in connection, with washing machines used in laundry work, where it is required to drive the machine first in one direction a certain number of revolutions and then reverse it and drive it in the opposite direction a certain number of revolutions, but it .will be understood that my invention may be used on other machines where it is desired on the line 33, Fig. 1; Fig. 4, is an enlarged sectional view on the line Fig. 1;. Fig. 5, is a sectional perspective view of part of the turbine wheel; Fig. 6, is a detached sectional view illustrating a detail of the invention, and Figs. 7, 8 and 9, are

= detailed perspective views of parts of the apparatus. to the drawings, A is the body i of.'.'a:wash1ng machinehaving a shaft B extending throughone end.

ID-" iege; frame secured to the body of the washing machine in any suitable manner, and this frame supports the; motor casing E and the bearings for the gearing between the motor and the shaft- B of the machine. The casingE is made in two parts 6, e bolted together as shown, and within the casing is a turbine wheel F mounted on the shaft F adapted to bearings e in the casing E. The shaft F has at its inner end a pinion g, Fig. 2, which meshes with a gear wheel G on a shaft G adapted to bearings e and d. This gear wheel is mounted in the present instance on an elongated hub of a pinion G which meshes with a gear wheel the nozzle C. I

. b secured to the shaft l3. will beunden stood, however, that thisarrangemen't of gearing may be modified vitl1out departing from the essential features of my invention.

The gearing will depend entirely upon the speed desired for the drivenelement.

The turbine wheel F'is made double, as shown in Figs. 2- and 5, having two lines of pockets or blades, one facing in one direction and the other in the opposite direction.

These blades are formed; on rings fff bolted or riveted to the body of the wheel as at F.

There aretwo nozzles (land G',-one arranged at one side of the casing and the other arranged at the other side of the eas ing, the nozzle C projects a jet against the blades f while the nozzle 0'- projects a jet against the blades f. and I provide means for directing fluid under pressure to either nozzle. It will be noticed. that each nozzle is removable from the casing and. is made as illustrated and described in an application for patent filed by meieven date here: with.

I is a valve chest in which isa valve 2' ha ving a stem 2 which passes through a stuffing box i i 1 is a fluid admission "pipe comu'iunioating with one end of the valve casing, e. is a pipe leading from the same end of thevalvecasing to the nozzle C, and c a pipe leading from the opposite end of the valve casing to On the end of the valve rod 1' is a head 5 adapted to guidways in an extension of the valve chest. and mounted between the head and the body of the chestis a coiled spring I tending to keep the bee d projected and the valve in its forwardposition, which will close the passage leading to the pipe 0 and open the passage leading to the pipe 0.

Mounted in ahearil lg on 'therasing E is a shaft M on which is mounted a hub m hav I ing four arms m in. the present instance. On the gear wheel I) is a pin'l)" which pro jects so as to contact with the arms m, mov ing the hub in a quarter turn at each revolution of the gear wheel I). Loose on the opposite end of the shaft M is a cam N which actuates the head 2' and shifts the valve to the position shown in Fig. 1. When the cam is clear of this head the spring returns the valve to its forward position. Keyed to the shaft is an arm n which is engaged by a pin 1:. on the cam N as shown in Figs. 6, 8 and 9,

and this arm move intermittently with the hub m. A spring'm onthe shaft tends to keep the hub m in frictional contact with thebar of the shaft so that. it will not move past the position in which the pin 1) leaves it, thus insuring the proper movement of the parts. In the present instance the cam N will be moved after the wheel 6 has completed four revolutions. This movement of the cam will reverse the valve so as to reverse the direction of movement of the wheel f I). Then it will make four revolutio11s in i actuating the said valve, the same including a spring tending to hold it in one position, and a periodically operated cam for movin it to another position against the action or said spring.

2. The combination of a turbine motor, an

inclosing casing, a wheel therein, two sets of blades on the periphery of .said wheel, one set facing in one direction and the other facing in the opposite direction, two nozzles, one in line with one set of blades, and other in line with the other set of blades, a valve controlling the flow of fluid to either nozzle, and automatic mechanism for shifting the valve so that the wheel is first driven in one direction and then in the opposite direction, said mechanism including a device tending to retain said valve inone of its two positions, and means for periodically moving it.-

against such device to its other position.

3. The combination in a fluid motor of a casing, a shaft, a wheel having two sets of blades thereon, one set facing in one direction and the other facing in the opposite direction, two nozzles, one in line with one setof blades and the other in line with the other set of blades, a valve capable of directing motive fluid to either of. said nozzles, a shaft,

i t l l i hub for moving the valve in the opposite di' rection.

4. The combination in amotor of a casing, a wheel mounted therein, having two sets of blades, one facing in one direction and the other facing in the other direction, two nozzles, one in line with one set of blades, and

the other in line with the other set of blades,

a valve chest communicating with both nozzles, a valve therein, a shaft, a cam loose on the shaft, an armed hub fast to the shaft, an arm also fast to the shaft. and arranged to engage the cam, a driven wheel having a pin thereon arranged to engage the arms of the hub so as to automatically shift the valve to reverse the motor.

5. The combination in a motor of a casing. awheel mounted therein having two sets of blades, one facing in one directionand the other facing in the opposite direction, two nozzles facing in opposite directions .and one in linewi-th one set of blades and the other in line with the other set of blades, a valve for controlling the flow of fluid to the 11ozzles, a shaft, a hub thereon ,having'arms, a pin on a driven element arranged to strike the arms and turn the hub and-shaft, a cam. loose on said shaft and arranged to actuate the valve, a pin on the cam and an arm keyed to the shaft for moving the cam.

6. The combination in a. turbine motor of a shaft, two sets of vanes on said shaft, one set facing 1n one direction and the other set ,facing in the opposite direction, a casing incloslng the vanes, two nozzles, one on one side of the casing and in line with one set of vanes and facing in one direction, the other on the other side of the casing and in line with the other set of vanes and facing in the opposite direction,- a valve casing common to the two nozzles, a pipe connecting one end of the casing with one nozzle, and a pipe connecting the other end of the casing with the other nozzle, a fluid supply pipe connected with one end of the casing, a valve in -,the casin a valve rod, a head on the valve rod, a spring tending to force the head and valve forward and means actuated by a driven element for shifting the valve atintervals.

In testimony whereof, I have signed my name to this specification, in the presence of 5 two subscribing witnesses.

a hub on the shaft provided with arms, a wheel having a pin thereon engaging the armedhub, a spring for moving the valve 1 in one direction, and a cam controlled by the i THOMAS SUMNER PATTERSON.
